WILLIAM MILLER DIGHT, OF JACKSON CENTER, PENNSYLVANIA.

- HORSESHOE.

To all whom it may concern.

Be it knownthat I, WILLIAM MILLER DIGH'I, a citizen of the UnitedStates, residing at J ackson Center, in the county of Mercer and Stateof Pennsylvania, have invented certain new and useful Improvements inHorseshoes, of which the following is a specification.

My present invention relates to improvements in horseshoes; and the mainobject of my invention is the provision of a shoe provided with calkswhich are detaohably secured in place, a novel means being providedwhereby the calks can be dispensed with without impairing the shoe andcan be readily attached, as

the recesses for receiving the same if cloggedare very readily cleaned.

' To attain these objects the invention consists of novel features ofconstruction, substantially as disclosed herein.

In the accompanying drawings, Figure 1 is a bottom plan view of a shoewith the toe-calk removed to show the construction of the slot therein.Fig. 2 is a top plan-view of one of the calks. Fig. 3 is an end view ofone of the calks; and Fig. 4 is a section through a portion of a shoeand a calk, showing an extra locking means to hold the calks in place.

Referring to the drawings, A designates the shoe, which is provided atits toe with the dovetailed slot 15, which converges from the end C toits end D, while the heels of the shoe are provided with similar slots Eand F. Adapted to be secured in the various slots of the shoe are thetoe-calks G and the heel-calks H, which are of substantially the sameconstruction, but of difierent lengths, as will be seen. These calks areeach made substantially triangular in cross-section, being provided upontheir lower sides with the dovetailed projection or rib J, whichconverges toward its end L, as clearly shown in Fig. 2. This dovetailedprojection is adapted to lit in the dovetailed groove or slot B and beslid from the wide end toward the narrow end thereof, thus wedg-Specification of Letters Patent. Application filed September 19, 1904-Serial No. 225,075.

Patented Aug. 1, 1905.

ing the dovetailed projection within the slot or groove, so as to bepractically rigid with the shoe, the heel-calks being secured in placein a similar manner.

'In order to prevent the calks from being knocked or jarred from thegroove, I provide upon the upper face of each calk, near the narrow endthereof, small groove N, terminating in an opening or socket O, in whichis adapted to fit the hooked end of the wire or rod P, so that when thecalk has been pushed home the outer end Q, of the wire or rod can bebent forward or upward and engage the shoe, thereby holding the calkrigidly in the wedged position.

From the foregoing description, taken in connection with the drawings,it is evident that I provide a horseshoe that is provided withdetachable calks, which is the embodiment of simplicity, durability, andinexpensiveness, thus providing a thoroughly efficient and practicaldevice.

What I claim as new, and desire to secure by Letters Patent, is-

1. A horseshoe comprising a shoe proper provided at its toe and heelswith depressed dovetailed grooves, calks provided with ,dovetailedprojections adapted to fit within said grooves and a rod provided withoppositelyarranged hooked ends engaging the calk and outer face of theshoe.

2. A horseshoe consisting of a shoe proper provided with a dovetailedconverging groove at the toe and heel thereof, acalk provided withdovetailed converging projections adapted to fit within said grooves anda rod provided with oppositely-arranged hooked ends engaging the calkand outer face of the shoe.

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM MILLER DIGHT.
